Lenovo has revealed the ‘world’s first foldable PC’ which is a part of its flagship ThinkPad X1 series to be launched in 2020. While foldable smartphones are making headlines, this is the first time a foldable device has been introduced which will soon replace your laptop. The foldable ThinkPad X1 rolls out a 13.3-inch 2K OLED screen in a 4:3 aspect ratio, and when folded in half it turns into two 9.6-inch displays.
